Start Your LLM JourneyEvery LLM and human data role we staff, with LATAM rates
Ten profiles across the training-data stack. Each one is a dedicated hire working your hours, not anonymous crowd throughput — with a quality metric written into the contract.
| Role | What they produce | Quality bar | LATAM rate |
|---|---|---|---|
| RLHF & Preference Optimization | Pairwise comparisons, rankings and critique loops that turn human judgement into reward-model training data for PPO and DPO pipelines. | Inter-annotator agreement κ ≥ 0.80 | $26–36/hr |
| Supervised Fine-Tuning (SFT) Data | Instruction-response pair creation, taxonomy tagging and rubric execution for domain-specific fine-tuning in English, Spanish and Portuguese. | Label accuracy ≥ 95% on golden sets | $23–33/hr |
| Data Collection & Creation | Net-new human-generated data: prompts, long-form writing, speech recordings, screen and device capture, and scenario scripting for edge cases your logs never contain. | Spec compliance ≥ 97% at acceptance sampling | $18–28/hr |
| Model Safety & Red Teaming | Adversarial testing of deployed and pre-release models: jailbreaks, prompt injection, harmful content probing and agentic misuse scenarios. | Attack coverage across 12+ harm categories | $28–40/hr |
| Model Evaluation & Benchmarking | Human evals, LLM-as-judge calibration, golden datasets and regression suites so every prompt or model change is measured instead of guessed. | Judge-human correlation tracked per release | $25–35/hr |
| Multilingual & Localization Data | Native Spanish, Portuguese and English data creation, translation review, and locale-aware safety labeling for models serving the Americas. | Native reviewer sign-off on 100% of batches | $20–30/hr |
| Code & Agentic Traces | SWE-bench style task annotation, tool-calling traces, UI intents and agent trajectories labeled by engineers who read and run the code. | Functional correctness verified by test runs | $30–45/hr |
| Multimodal Annotation | Vision, audio and video labeling: bounding boxes, segmentation, transcription, diarization and cross-modal alignment checks. | Annotation precision audited on blind golden sets | $18–30/hr |
| RL Environments | Task environments, simulators and verifiable reward functions for training and evaluating agents on real software workflows. | Deterministic reproduction on 100% of tasks | $32–48/hr |
| Domain Expert Networks | Licensed and credentialed professionals — clinicians, lawyers, accountants, engineers — writing and reviewing data where a generalist annotator cannot. | Credential verification on every expert | $35–70/hr |
